Abstract
The invention discloses coloring liquid for chemically coloring black on outer surface of a copper product. The coloring liquid comprises 3 to 25% of K2S, and 75 to 97% of H2O. The coloring method comprises the following steps: 1, grinding or blasting the outer surface of the copper product to remove copper oxide on the surface, and then brushing the outer surface to remove attached ash; 2, uniformly coating the coloring liquid on the outer surface of the copper product; 3, removing the coloring liquid residual on the outer surface; 4, standing, and then drying the outer surface coated with the coloring liquid; 5, coating fluorocarbon coating on the dried surface, isolating from air and ultraviolet rays in order to protect a coloring film. With the adoption of the coloring liquid and the coloring method, the requirements of artware can be met, and meanwhile, the color is uniform and bright; the components are simple and pure, thus the cost can be reduced, and the efficiency is high.
Description
Technical field
The invention belongs to non-ferrous metals processing field, particularly to a kind of copper product outer surface chemistry black coloring liquid and
It color method.
Background technology
The sculpted surface made by metal presents the color of matrix, and matrix color is the abundantest, does not has stereovision, it is impossible to reach
To the artistic effect needed.Coloring liquid is smeared in metal surface so that the art work or carving although prior art also has
Mould the use finally presenting color.But the general complicated component of coloring liquid of the prior art, and color is the purest,
Owing to reacting containing many kinds of substance, so that the color finally presented has inconsistent or unshapeliness is deep mixed
Phenomenon.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides one can reach artware requirement,
The color even simultaneously presented is bright-coloured, composition copper product outer surface chemistry simply purely black coloring liquid and
Color method.
Technical scheme: for achieving the above object, the present invention provide a kind of copper product outer surface chemistry the coloring liquid of black,
Described coloring liquid is the K containing 3～25%2The H of S and 75～97%2O is constituted.By the K containing 3～25%2S and 75～97%
H2The coloring liquid that O is constituted is coated in copper product surface, and not only the simple raw material of formula is single but also low cost efficiency high, simultaneously
Make last copper product surface color enrich bright-colored unanimously, effect is various, it is easy to construction.
Preferably, described coloring liquid is the K containing 5～20%2The H of S and 80～95%2O is constituted.By containing 5～20%
K2The H of S and 80～95%2The coloring liquid that O is constituted is coated in copper product surface, and not only the simple raw material of formula is single but also use more
A small amount of K2S makes low cost efficiency high, make simultaneously last copper product surface color enrich bright-colored unanimously, effect
The most various, it is easy to construction.
Most preferably, described coloring liquid is the K containing 10～15%2The H of S and 85～90%2O is constituted.By containing 10～15%
K2The H of S and 85～90%2The coloring liquid that O is constituted is coated in copper product surface, and not only the simple raw material of formula is single makes cost
Inefficient high, use 10～the K of 15% simultaneously2S makes the color more bright colors on last copper product surface more consistent, easily
In construction.
A kind of copper product outer surface chemistry as described above black coloring liquid color method, step is as follows:
Step one: first polish copper product outer surface or sandblasting, removes copper oxide surface, and then outer surface is entered
Row scratch brushing removes floating ash；By first made by the Impurity removal on copper product surface can be preferably with copper at follow-up coloring liquid
The copper contact of product surface produces reaction thus presents black.
Step 2: by coloring liquid uniform application at the outer surface of copper product；Uniform application is in order to preferably present unification
Color, color is consistent.
Step 3: remove the coloring liquid that exterior surface remains；Unnecessary coloring liquid is removed, cost-effective.
Step 4: after standing, the outer surface scribbling coloring liquid is dried process；Coloring liquid energy is made by dried
Enough make to colour faster, and avoid follow-up operation to cause coloring liquid to cause the broken of coloring liquid layer owing to not thoroughly being dried
Bad.
Step 5: dried surface spraying fluorocarbon varnish, coloring film is protected by by isolation air and ultraviolet.Pass through
Spraying fluorocarbon varnish makes to play a protective role the copper product outer surface coloured after processing, and prevents external environment pair
The erosion of color so that color the most bright-coloured can be not easy decolouring.Wherein, coloring liquid the principle of black and is: 2Cu+
2K2S+O2+2H2O=2CuS ↓+4KOH.
Beneficial effect: the present invention compared with prior art has the advantage that
(1) present invention is by appropriate K2S and appropriate H2The coloring liquid that O is constituted is coated in copper product surface, not only joins
The simple raw material in side is single and low cost efficiency high, makes last copper product surface color enrich bright-colored one simultaneously
Causing, effect is various, it is easy to construction.
(2) present invention is by first made by the Impurity removal on copper product surface can be preferably with copper at follow-up coloring liquid
The copper contact of product surface produces reaction thus presents black.Then uniform application is in order to preferably present unified
Color, color is consistent.Make coloring liquid enable to colour faster by dried again, and avoid follow-up operation to make
Coloring liquid is become to cause the destruction of coloring liquid layer owing to not thoroughly being dried.Make process finally by spraying fluorocarbon varnish
After the copper product outer surface coloured play a protective role, prevent the external environment erosion to color so that color energy
The most bright-coloured enough being not easy is decoloured.
